Constants and Variables Constants and Variables are the two types of symbols in algebra. Constant: A symbol which has a fixed numerical value is called a constant. For example: 2, 5, 0, -3, -7, 2/7, 7/9 etc., are constants. Number of days in a week represents a constant. In the expression 5x + 7, the constant term is 7.
Constants and Variables Variables: A quantity which has no fixed value but takes no various numerical values is called a variable. For example: Temperature at different times of a day represents a variable. The height of a student in your grade is a variable, as it varies from student to student. A variable is denoted by a letter like x, y, z, u, v etc.
Examples Examples on Constants and Variables: ( i ) In 2a , 2 is a constant and a is a variable. (ii) In -7mn , -7 is a constant and m and n are variables. (iii) In 3x , 3 is constant and x is variable but together 3x is a variable. (iv) If 3 is a constant and x is a variable, then 3 + x, 3 - x, 3/x, 3x, x/3, etc., are also variables. So, we conclude that the combination of a constant and a variable is always a variable.
Trade-off functions Trade-off functions express how much of one objective has to be sacrificed to increase the value of another objective by one unit.
Functions
Linear Functions An equation whose graph is a straight line is called a linear function. A linear function has an equation that can be written in the form of
Nonlinear Functions - Q uadratic function Equations whose graphs are not straight lines are called nonlinear functions. Some nonlinear functions have specific names. A quadratic function is nonlinear and has an equation in the form of
Nonlinear Functions - Cubic function Another nonlinear function is a cubic function. A cubic function has an equation in the form of
